Strange as it may seem, there have been many races lost in oval track, off-road and endurance competition due to the OEM alternator stud failing and the subsequent loss of electrical power. To prevent this from ever happening, conscientious engine builders rely on ARP’s “bulletproof ” alternator studs.

They’re made from a premium grade 8740 chrome moly steel alloy and heattreated to a nominal 200,000 psi tensile strength. They are very rigid and won’t bend under the stress of competition, eliminating problems with alternator pulley alignment. Here’s more reliable “insurance” from the innovators at ARP Includes a 12-point nut and flat washer.

We have an assortment of premium quality stainless steel and black oxide finish 8740 chrome moly bolts for the most popular applications. Washers included.

These bolts are also available as part of our complete Engine & Accessory Kit packages.
